ISS FlyOver reads the NASA Human Space Flight (HSF) Realtime Data RSS feed. That feed that provides up to date sighting information about the ISS. If the RSS feed is unavailable for any reason, the ISS FlyOver app will launch a web browser so you can see sightings info.

* Data Connection

ISS FlyOver relies on a data connection to the internet for up to date sightings data.

* Known Issues

Issue: Since date and time in the RSS feed are local to the selected city, the ETA should also reflect that. However, the app is currently using the local time of the device to calculate ETA rather than local time of the selected city.
